Hi guys.. I know this is an old thread, but i'm trying to get the line chart for overlay as I think that's the best way to view overlay charts.


I changed DRAW_HISTOGRAM to DRAWLINE but it now displays a lot many lines. Refer to the picture below.


Overlay Chart

I think this has to do because of these pieces of code (and possibly others too). Because this indicator was written for Candles, thus we have Bull/Bear and the two outlines. Can someone help to correct this please?

   SetIndexBuffer( 2, ExtMapBuffer3 );
   SetIndexBuffer( 3, ExtMapBuffer4 );

   SetIndexStyle( 0, DRAW_LINE, DRAW_LINE, 1, BullBarColor );
   SetIndexStyle( 1, DRAW_LINE, DRAW_LINE, 1, BearBarColor );
   SetIndexStyle ( 2, DRAW_LINE, DRAW_LINE, 1, BullBarColor );
   SetIndexStyle( 3, DRAW_LINE, DRAW_LINE, 1, BearBarColor );

   SetIndexEmptyValue( 1, 0.0 );
   SetIndexEmptyValue( 2, 0.0 );
   SetIndexEmptyValue( 3, 0.0 );


   return( 0 );

The linechart is same as    simple moving average  period one  close price

So why not place that moving average on the chart with your candlestick ???
